Technical solution and structural characteristics of the roller external ladder chain

Technical solutions and structural characteristics

Main components

• Inner link plate, outer link plate, bushing, roller, and pin：These components together form the basic framework of the step chain.

Innovation points

• Side scroll wheel settings：A side roller is mounted on the pin and located outside the outer link plate, which helps the chain run smoothly.

• Dual position lubricated bearings application：By setting up the first self-lubricating bearing and the second self-lubricating bearing, the lubrication holes are evenly distributed between the inner and outer sides, ensuring full and uniform self-lubrication between the drum and the pin shaft structure.

• Double-sealed fit：Using specialized sealing rings for double-seal cooperation improves the sealing safety.
